Answer:
Correct answer is:
B. Both have populations that are not very diverse.
C. Both are agricultural.
Step-by-step explanation:
A is wrong because this are small communities and don't have developed educational system. Only 20 percentage of people in Phillips County has higher education.
B is correct, because in Phillips County we have a large percentage of American Indians, but also Asian, Hispanic, and of course descendants of Europeans. The same goes with Nan, a mixture of different ethnicities and religions.
C is correct as most of the people are working in agriculture, and this is a main source. Both areas are rural.
D is not correct of course, because as we have said most people are farmers. Practically no one works in large factories.
